MINE-CHECK HOLDER.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed April 20, 1914. Serial No. 833,188.

To all whom it may concern:

Be it known that I, WVILLIAM A. WIL LIAMS, a citizen of the United States of America, and resident of Barton, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Mine-Check Holders, of which the following is a specification.

This invention relates broadly to minecheck holders, and it has for its primary object to provide a check receptacle having mechanism by means of which a deposited check is retained against displacement until the car to which it is attached assumes a predetermined inclination, as at the dumping point, whereupon it is automatically released.

A further object is to provide an automatic check holder the check holding and releasing mechanism of which can not be actuated to release deposited checks by shocks due to collisions or bumping of cars.

With the above-recited main objects in view, the invention resides in the features of construction, arrangement of parts and nations of elements which will hereinan r be fully described, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of a mine car o cupying lor ling position, showing my check holder mounted thereon; Fig. 2 is a similar view showing the car occupying dumping position and showing the check holder iii-check releasing position; Fi 3 is an enlarged upper edge view of the check holder, detz-iched; Fig. 4 is a section on the line etl Fig. 3, showing the device in upright position with the mechanism incheck holding position; andFig. 5 is a similar sect-ion showing the device inclined to substantial; tho P35111911 assumed when the car ing position and showngthe I check releasing position. F 6 is a sectional view taken on the line 66, Fig

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views, 1 indicates generally a casing, preferably formed of metal and made rectangular in shape. Said casing consists, preferably, of a backplate 2 and an interfitting box-like cover 3, the latter being removably attached to said back-plate, as by means of screws 4. Said casing is adapted for mounting in any suitable manner upon a side of a mine-car, as

5, whereon it occupies a substantially upright position, as shown in Figs. 1 and 2. Provided in the upper edge of said casing is a check-receiving slot 6 which communicates with the upper end of a curved or inclined passage or runway 7 formed within a tube-like member. 8 which is of substantially rectangular form in cross section. The opposite, or lower, end of said member opens outward throughthe front edge of the casing and forms a spout through which checks may be discharged, as will hereinafter be explained. Pivoted intermediate its ends outside said runway is a lever 9 having fixed thereto or formed integral therewith at a point above its pivotal mounting a forwardly projecting arm 10 which, in the normal upright position of said lever, stands projected into said runway through an opening 11 provided in the rear side of the tube-like member a 8. said arm constitutes a guard which so restricts the capacity of said runway as to prevent the passage thereby of deposited checks 12, such checks being supported thereby, as shown in Fig. 4. A weight 13 carried upon the lower end of said lever 9 is designed to maintain the latter in upright position irrespectiv of the position assumed by the c uq, within which it mounted. thus mainuaining the arm or guard 10 projected into the runway in a position preventing the passage thereby," of checks except when said casing occupies the sharply inclined position which is assumed only when car assumes dumping position.

In order to 'zrevent free or i'inobstructed pendulum-like swinging vemcnt of the lever, which 'u'ouid resul. in the untimely release of dep able movement retarding device con ug of a small cylinder 14: in which operates a reciprocating piston 15, the latter being suitably connected to the free upper end of the lever 9,,a'siby a pitman or COIflllfiClill rod 16. Said piston ma be ,fitted more or less looselyin the der that air may pass thereby in enterng and exhausting from the cylinder, in which case no port for the passageiof air need be provided in said cylinder;,or small port may be pro led in the cylinder, as shown at 17, Fig. 5., if desired. In'either case, however, the pa sage for air must be so restricted that the air will be permitted to exhaust but slowly from the In this position checks, 1 provide suittually prevent the lever 9 from swinging to check-releasing position under the actuating influence of sudden shocks or jars, due to collisions and the like, communicated to the mechanism.

A suitable hinged cover, as 18, may be provided on the casing to overlie the slot 6 for excluding dust and foreign matter. A light-weight swinging closure 19 may be provided in the lower end of the runway, the lower or free end of which normally seats against a shoulder 20 provided in the bottom of said runway. WVhile not obstructing or impeding the discharge of a released check, said closure prevents tampering with the check-holding mechanism from the lower end of said runway, as by the insertion of a wire or other instrument.

From the foregoing it will be seen that checks are positively retained in my device until the car to which it is attached assumes a certain inclination. The checks are preferably ejected into a receptacle, chute, or the like (not shown) located at a suitable point on the dumping tipple.

hat is claimed is- 1. In combination with a mine-car, a check holder mounted on the car, said holder comprising a suitable inclosure having a passageway for checks therethrough, a guard movable into and out of said passageway normally maintaining the latter closed against the passage of checks therethrough, means whereby said guard is automatically withdrawn when the car assumes a predetermined position, and means limiting the rapidity of said withdrawal.

2. In combination with a mine-car, a check holder mounted on the car, said holder comprising a suitable inclosure having a passageway for checks therethrough, a guard supported outside said passageway and movable into and out of the latter, means normally maintaining said guard projected into said passageway for closing the latter against the passage of checks therethrough, said means automatically efiecting the withdrawal of said guard only when said car assumes a predetermined inclination.

3. In combination with a mine-car, a check holder mounted on the car, said holder comprising a suitable inclosure having a passageway for checks therethrough, a lever pivoted outside said passageway, a guard carried by said lever and adapted to move into and out of said passageway with the swinging movement of said lever, gravity controlled means normally holding said lever in a position wherein said guard is projected into said passageway for closing the latter against the passage of checks therethrough, said means being adapted to effect the withdrawal of said guard when said car assumes a predetermined inclination, and means limiting the rapidity of such withdrawal.

4. In combination with a mine-car, a check holder mounted on the car, said holder comprising a suitable inclosure having a passageway for checks therethrough, a pivoted lever located outside said passageway and' carrying a guard which is movable into and out of said passageway with movement of said lever, gravity controlled means normally maintaining said lever in upright position with said guard projected into passage-closing position, said means being adapted to swing said lever to guard-withdrawing position when the car assumes a predetermined inclination, and means connected to said lever whereby movement of the latter to guard-withdrawing position is retarded.

5. In combination with a mine-car, a check holder mounted on the car, said holder comprising a suitable inclosure having a passageway for checks therethrough, a guard normally disposed within and withdrawable from said passageway, said guard being designed to normally maintain said passageway closed against the passage of checks therethrough, a pivoted lever mounted outside said passageway by which said guard is carried, a weight carried by the lower end of said lever for normally main taining the latter in a position holding the guard in passage-closing position, and means limiting the rapidity of guard-withdrawing movement of said lever.

6. In combination with a mine-car, a check holder mounted on the car, said holder comprising a suitable inclosure having a passageway for checks therethrough, a guard movable into and withdrawable from said passageway, said guard being normally disposed within said passageway for maintaining the latter closed against the passage of checks therethrough, a pivoted lever mounted outside said passageway by which said guard is carried, a weight carried by the lower end of said lever for normally maintaining the latter in a position holding the guard in passage-closing position, and means limiting the rapidity of guard- V withdrawing movement of said lever, said means comprising a cylinder and a reciprocable piston in said cylinder, said piston having connection with said lever.

In testimony whereof, I afiiX my signature in presence of two subscribing witnesses.

WVILLIAM A. WILLIAMS.
